PJ40215: CROCESSORS.DC REPORTS INCORRECT CEC UTILIZATION FOR LPARS USING SPECIALTY P
Closed as program error.

APAR NUMBER: PJ40215 PRODUCT: z/TPF FUNCTIONAL AREA: CONTINUOUS DATA COLLECTION (CDC) SHIPPED IN PUT: 9 ABSTRACT: CDC reports incorrect CEC utilization for logical partitions using specialty processors with PJ30885 applied PACKAGE CONTENTS: Source Segments: (C) base/include/tpf/c_icdc.h (C) base/rt/cdcp.c Object Only Binaries: (C) base/oco/lib/libcdc_lib.a Configuration Independent Binaries: (C) base/load/CDCP.so (C) base/load/JCC1.so (C) base/load/JCI4.so (C) base/load/JCI5.so (C) base/obj/cdcp.o Support Files: base/lst/cdcp.lst base/lst/CDCP.map base/lst/JCC1.map base/lst/JCI4.map base/lst/JCI5.map OTHER BINARIES TO BUILD: YES (C) <sys>/load/JCD4.so COMMENTS: CDC code calculates CEC utilization percent by dividing the total utilization of all processors assigned to the LPAR by the total count of general purpose processors in the CEC. For LPARs with specialty processors assigned this will result in incorrect CEC utilization percent values.
SOLUTION: The chosen solution is to update CDC to report LPAR CPU counts and utilization values solely based upon the shared general purpose processors. With this APAR applied, the CPUs column will be the number of shared general purpose CPUs assigned to the LPAR. The three utilization columns (LPAR utilization, Capped utilization percent, CEC utilization percent) will represent utilization of only the shared general purpose processor assigned to the LPAR. LPARs which have dedicated processors assigned or have only specialty processors assigned will be reported upon but their values (CPU count and utilization values) will be zeros. COREQS: NO None. MIGRATION CONSIDERATIONS: NO None.
